Some users may encounter the problem of the handlebar shaking back and forth when using a scooter. The handlebar will turn backwards every time you accelerate, and every time you brake, the handlebar will also turn backwards, which will bring a bad riding experience.
The reason why the handlebars shake back and forth is that the scooter's folding part is a little loose. You can use a No. 10 socket tool to tighten the nut under the folding part and try to adjust the tightness several times.
The video below shows you how to do it.
